The present study was conducted to survey and document the ophidian fauna of Reiek Community Reserved Forest, Mamit District, Mizoram, Northeastern India for the first time. Extensive survey for studying the ophidian fauna of Reiek Community Reserved Forest, Mamit District, Mizoram was conducted from October 2018 to September 2019 by using Visual encounter survey (VES) method for sampling. Specimens were caught with the help of a snake hook, tongs and also by hand, then kept in the snake bags. They were euthanized and fixed in 10% buffered formalin and later transferred in 70% ethanol in the

There is no record on the prevalence of parasites of snakes in Mizoram. This study was undertaken in an attempt to identify common gastrointestinal parasites in the king cobra Ophiophagus hannah. In this preliminary survey, necropsy was performed on four individuals collected from different localities within Mizoram during January 2015 to June 2016. Of the 4 snakes examined, 1 was found infected with cestode, nematode and acanthocephalan. The Capillaria sp. and Kalicephalus sp. collected from O. hannah in the present study was morphologically identified but molecular identification could not be done due to insufficient specimen. Acanthocephalan cystacanths were collected from the intestinal lining and were morphologically identified as belonging to the family Giganthorhynchidae. Metacestode of Taenia sp. was collected from the body cavity and was morphologically identified while molecular characterization could not be done as only a single specimen was collected. Accurate identification is very important in understanding the geographical distribution and biodiversity of parasites. However, the identification of parasites to the species level based solely on morphological analysis might be risky.

To survey and document the Ichthyophiids caecilians fauna in Mizoram, northeastern India with anticipation on the occurrence of other species other than the earlier recorded Ichthyophis. During extensive surveys conducted, 22 specimens of striped Ichthyophis species were collected from Mizoram, India, obtained over a period of 9 years from 2010 to 2019. Standard procedures for sexing, preservation and storage of specimens were followed. All nomenclature herein follows the taxonomy as suggested in literatures and identification solely based on the morphology. Four distinct striped Ichthyophis species were identified on the basis of their morphological characters. Out of which, two species have already been reported from the state. In this study two additional species of striped Ichthyophis namely, I. garoensis and I. sendenyu have been reported. This report represents a new state report of the species and also extends their geographic distribution range.

The breeding behavior of Fejervarya multistriata was studied from the selected study sites in Mizoram for over three years between 2016 and 2019. In natural condition, breeding took place in group. The advertisement call of males consisted of a series of notes emitted at an interval of 0.1–0.4 s where the frequency spectra had a dominant band at 2670.1172 Hz and the band width ranges from 2497.8516–28422.3828 Hz. Morphometric measurements showed that females are larger than males with snout-vent length of 45.55 ± 1.54 mm vs 33.77 ± 1.03 mm, respectively. The clutch sizes ranges from 488 to 1035. We found that the calculated ‘t’ value 0.03 is less than the ‘p’ value, i.e. 1, therefore there is no correlation between SVL of females and clutch sizes.
